HAND-PROTECTO R.

SPECIFICATION forming part of Letters Patent No. 276,231, dated April 24, 1883.

Application filed September 4, 1882. (No model.)

To all'whom it may concern:

Be it known that '1, JOHN DOYLE, of Hoboken, in the county of Hudson and State of New Jersey, have invented an Improvement in Hand-Protectors, of which the following is a specification.

The object of this invention is to enable a workman to grasp any article at some distance from the hand, so that the hand may be protected from danger.

Itis well known that-circular saws very often injure the hands of the workmen. This improvement enables the piece of wood to be grasped and held While being passed over the saw, the hand of the Workman not coming dangerously' near to the saw. The same instrumentis usefulin handlingarticles that are hotsuch as crucibles, castings, forgings, &c.-'wth out the risk ot' the hand being burned, and the instrument maybe used for any other purpose wherever available.

In the drawings, Figure l is a plan View of the implement with the hand applied to the same. Fig. 2 isa side view, and Fig. 3 is a section at the line a' a'.

I make use of a stock, a, or bar, upon which is received the shell b, of sheet metal or other material, having at its ends the anges c d, that are turned downwardly.

h h h2 h3 h4 are longitudinal shafts, bars, or tubes that pass through the llanges c and d of the shell b, and at the back end each shaft is bent downwardly as a crank, and terminates with aloop or finger-piece, k, of suitable shape to receive the fin gers or against which the tinger may rest; and at the forward end the respective longitudinal shafts are bent down- Wardlyand curved, and provided with windings or pads of leather, cotton, or other suitable materialw-such as metal or asbestus-,to form the thumb Z and fingers m n op. The loops koriinger-pieces are in a position adapted to receive the fingers of the hand, and the loop 7c the thumb, as shown in Fig. 1, and the hand is above the stock a, so that the instrument is grasped by the pressure of the ngers and thumb as they seize and hold the loops,

the loops and crank-arms swinging as the iingers are closed, and in so doing the bars or longitudinal shafts h h' h2 h3 h4 are partially 5o turned, and the fingers and thumb ofthe handprotector receive a motion analogous to that of the human hand; hence the protector can be made to grasp and hold a piece of wood or metal, (shown at 10,) or let go of the same, and

the fingers of the protector being so far away from the operatives hand that it is not necessarily brought into dangerous proximity to a circular saw, or to any place where there is risk of injury from cutting-tools, heat, or any 6o other source of danger,and at the same time the protector grasps the article to be operated upon with the required firmness. This protector is a new article of manufacture.

I am aware that artificial hands have been made use of; but the fingers of such handsare not adapted to being moved by the actual ngers of the natural hand.

I do not limit myself to the materials employed, as the shafts that extend from the 7o natural fingers to the articial ngers may be of Wood or other suitable material, 'and solid or hollow, and the shell may be in the form of a frame, if desired. In some instances `it will not be necessary to provide more than two 7 5 fingers and the thumb.

I claim as my invention- 1. The combination, with the shell a, having the anges b c, of the shafts passing longitudinally through the flanges, the crank-shaped So ends and loops to such shafts, the thumb and linger-pieces at the bent Vends of such shafts,

and the stock a, substantially as set forth.

2. The hand-protector having artiicial 1ingers and thumb at one end of the instrument, 8 5
